Host SSH daemon, if enabled, must ignore .rhosts files

SedangLevel 1Otomatisvmware

Deskripsi

Ignoring .rhosts files is crucial in hardening the SSH daemon on the host, ensuring that trust relationships are explicitly defined and not implicitly accepted, thereby reducing the attack surface. The audit reads /etc/ssh/sshd_config and requires IgnoreRhosts yes (unset = OpenSSH default yes). Runs in the ESXi Shell (busybox sh) as root.

Cara pemeriksaan

Metode audit: Perintah shell

shell

f=/etc/ssh/sshd_config; [ -r "$f" ] || exit 1
v=$(awk 'tolower($1)=="ignorerhosts" {print tolower($2); exit}' "$f")
case "$v" in '') echo compliant ;; yes) echo compliant ;; *) echo "IgnoreRhosts $v" ;; esac

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

To remediate this recommendation, set IgnoreRhosts yes, restart SSH if authorized, and verify .rhosts-based trust is ignored.
